Generated audio signal granting access to resource
A transmitting computing system's use of an audio signal to grant users of receiving computing systems access to a resource. These other receiving systems are in close proximity to the transmitting system so that they hear the audio signal on their microphones.

When an unknown device is introduced, it is initially connected to the guest network and can only communicate with the hub and with a wide area network (WAN). The unknown device is prohibited from communicating with the secure network and any device connected to the secure network. The unknown device provides credentials to the hub, which are verified with a secure database, such as a blockchain ledger, that provides manufacturer device information and certification. Upon authentication, the hub permits the identified device to connect to the secure network. The hub may also configure the now identified device for security and operational parameters. The hub may also retrieve network traffic pattern information from the secure database and use such information to monitor normal expected activity from the identified device. |

Mutual authentication system
Mutual authentication techniques are described in this patent document. For example, when a first person calls a second person, neither of them know that the other person is who he or she says he or she is. Thus, after a second person receives the call, the second person is asked to authenticate himself or herself using a user device. After the second person logs into his or her account, the second person can input on the user device a one-time passcode to authenticate the first person. The user device sends the passcode to an authentication server that allows the first person to send back the inputted one-time passcode to the second person. Upon receiving the inputted one-time passcode, the second person can use his or her user device to indicate that the one-time passcode is correct so that the second person can be authenticated to access the first person's account. |

Nanocomposite of a nanoporous material and an active material and method of synthesizing thereof
In an embodiment, an active material-based nanocomposite is synthesized by infiltrating an active material precursor into pores of a nanoporous carbon, metal or metal oxide material, and then annealing to decompose the active material precursor into a first gaseous material and an active material and/or another active material precursor infiltrated inside the pores. The nanocomposite is then exposed to a gaseous material or a liquid material to at least partially convert the active material and/or the second active material precursor into active material particles that are infiltrated inside the pores and/or to infiltrate a secondary material into the pores. The nanocomposite is again annealed to remove volatile residues, to enhance electrical contact within the active material-based nanocomposite composite and/or to enhance one or more structural properties of the nanocomposite. In a further embodiment, the pores may be further infiltrated with a filler material and/or may be at least partially sealed. |
